I would like to move my partition where I have Timeshift saved to my system SSD, as it is large enough at 250 GiB to hold an additional partition. I let save 1x daily + weekly. Is that too much writing for the SSD? Does this have a noticeable effect on its lifespan?
lifespan would be harder if you use as ramdisk; putting a swap drive on it and put up the swappiness. of you do daily weekly you have to decide your self 
as long you snapshot a stable system personal opinion snap shot in a cronjob has also its risc does not mesure the stableness, you have to see it then a snapshot and depend also what new you have that might not to be lost…a system snapshot you can say one a week or 2week is ok …; everyday is kinda over doing , mostly look what situation is…

i don’t think it affects the lifespan very much. But having the snapshots on a separate drive is more of a backup than having them on the same disk as your system is. Just take this into your consideration.

It concerns only the backup for the system, the data is backed up differently. And if the SSD is broken, I have other problems than the backup of /root. I only need the system backup for when something goes wrong with an update.
But something else: I set up TRIM via systemd with sudo systemctl enable fstrim.timer periodic. Does it trim the whole SSD or just the /root partition?
It will trim whatever is presented in the /etc/fstab.
